Profile

At Te Kura Kairūri I manage Hydrographic Surveying – teaching students and working with researchers from Surveying, Marine Science and Geology. I am a past student of the School of Surveying, and joined the staff in 2013.

I have been part of several research cruises on the university vessels. I teach practical hydrography skills around Dunedin Harbour and along the Otago Coast on the university research vessels Polaris II and Tūhura.

Prior to coming to Otago I completed my MSc (Hydrography) on the FIG/IHO/ICA recognised Category A course in Plymouth, UK. My background also includes several years working worldwide on a variety of hydrographic projects including charting, habitat mapping, oil and gas, renewables and offshore construction.

I thoroughly enjoy being at sea and like to learn, share and apply all aspects of nautical knowledge to my teaching.

Teaching

Research interests

  • Underwater acoustics, sound velocity measurement and application
  • Use of multibeam sonar in shallow coastal waters and deep offshore canyons
  • Using hydrographic data for more than one purpose - charting, geophysical analysis, habitat mapping, sea-level analysis
  • Hydrographic surveying in rivers and lakes
  • Hydrographic surveying education and development in NZ / Australasia

Research themes

Emily is also a member of the Coastal People: Southern Skies collaboration that connects communities with world-leading, cross-discipline research to rebuild coastal ecosystems.
